Have you wondered why your
oil filter needs to be replaced along with the oil at specific intervals?
The oil filter constantly removes dirt and impurities from the oil circulating around moving engine parts. Clean oil provides greater lubrication and lowers heat build up due to friction inside the engine.
But if your oil filter has poor quality, it can shorten the life of your engine and cause other parts to fail as well. This tiny part of your car's lubrication system plays a key role in protecting your engine from premature wear. All the moving parts in the engine need clean oil to properly lubricate them.
Tiny bits of metal chip off of various engine parts while it's running. If these bits of metal are allowed to recirculate through the oil, they could break off other bits of metal, which eventually will cause erosion in the engine. A quality oil filter helps prevent this erosion from taking place. The oil filter cleans the oil as it passes through the filter and prevents abrasive contaminants from damaging the parts in the engine.
It is very important to choose a high quality oil filter because the internal construction and quality of the filter has a tremendous effect on the life of your car's engine. Here ZENITH FILTERS a leading exporter and manufacturer of automobile spare parts offers top quality oil filters using the latest technology.
Working of an oil filter has been divided into few steps that will help you to understand better how an oil filter works-
Tapping plate/gasket - It is comprised of a center hole surrounded by smaller holes. Oil enters through the small holes on the outskirts of the tapping plate, also known as a gasket, and exits through the center hole, which is threaded to attach the part to your engine.
Anti-drain back valve - This is a flap-like valve that stops oil from seeping back into the oil filter from the engine when your automobile is not working.
Filter medium - This is the actual filter part of your oil filter is a medium composed of microscopic cellulose fibers and synthetic fibers that act as a sieve to catch contaminants before the oil reaches the engine. This medium is pleated, or folded, for greatest efficacy.
Center steel tube - Once the oil is filtered of any grit and debris, it passes back into the engine through a center steel tube.
Relief valve - When the engine is cold, such as upon start-up, it still requires oil. At low temperatures, however, the oil is too thick to pass through the filter medium. The relief valve allows small amounts of unfiltered oil into the engine to meet lubrication needs until the oil has heated enough to pass through the oil filter normally.
End discs - On either side of the filter medium lies an end disc, usually made of fiber or metal. These discs prevent unfiltered oil from reaching the center steel tube and passing into the engine. They are held firmly in place against the tapping plate by thin pieces of metal called retainers.
Vehicle's oil filter is designed not just to remove contaminants but also to keep the filtered and unfiltered oil in their proper areas as well as feed oil in a less-than-desirable form when the engine requires it.
